I've got the What to Expect book and I think it's fab. Yes, it doesn't go into 'Week by week' but let's just say I had some difficult decisions to make when the hospital thought my pregnancy was ectopic. The stuff I'd read in this book armed me with the right questions to ask the consultant. I'm not saying I couldn't have got that info elsewhere, but in any case my knowledge from this book enabled me to speak up and get involved in my treatment because (to the doctors' and nurses' surprise) I told them I understood what they were discussing. Knowledge is power!
